Hi, I've a physical server with a network interface that have 2 public ip. I configure the networking as follow:

iface enp2s0 inet manual

auto vmbr0
iface vmbr0 inet static
address X.X.X.Y (public ip for the Proxmox GUI)
netmask X.X.X.X
gateway X.X.X.X
bridge-ports enp2s0
bridge-stp off
bridge-fd 0

#public
up route add -net X.X.X.X netmask X.X.X.X gw X.X.X.X vmbr0
up ip route add 192.168.0.0/16 via X.X.X.Y dev vmbr0
up ip route add 172.16.0.0/12 via X.X.X.Y dev vmbr0
up ip route add 10.0.0.0/8 via X.X.X.Y dev vmbr0
up sysctl -w net.ipv4.ip_forward=1
up sysctl -w net.ipv4.conf.enp2s0.send_redirects=0

auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0

I installed NGINX to the Proxmox server as a reverse proxy for access the Proxmox GUI to the 443 port and everything work without issue. Now I would forward the NGINX logs with syslog to the SIEM that I installed to the vmbr1 but I can't reach the SIEM vm from the Proxmox server. How a can solve this networking issue?

Thank you

good morning, I would configure NGINX for sending logs with syslog, but I can't reach the vm to the vmbr1 from the Proxmox server.

You can find attached the network diagram
